v.To allwhom #may concern: .Y 'y y Be it known that I, HARRY B. HARTMAN,

a citizen of the United States, `residing at Scottdale, in the county of Westmoreland vandState .of Pennsylvania-,have invented certain new andVV useful Improvements inl y kfor use in` connection' with-water purication apparatus for bringing ozone into intimate contact'with Vthe raw water. v

Accordingly, as a vprimary object, the present invention contemplates a device which will thoroughlyniix thev oxidizing agent ozone with water in such a manner that the thorough treatment of the latter iii a practical and effective manner'is assured. That is to say, the invention proposesto provide a device wherein the ozone, which is heavier than air,'maybe distributed over a maximum surface area and poc-keted or trapped insuch a manner, that the water passing through the devicek will be agitated orbroken up while' inthe presence of and surrounded by the ozone.

A further object of the invention is to provide a mixer Ywhich may be readily taken apart and assembled, and by reason of its unitconstruction may beset upV in any .desired size to meet'the capacity of the various machines with which itmaybe used. in this connection, it is'proposed to provide a mixing; device which has a lwideiraiige of application from a preferred use' with relajtivelyV small household machines to a use with larger machines for other purposes. The v`construction, however is especially adaptable to what is known as a household machine, wherein economy of space is necessary, without sacrilicing thefacilities forinsuring the proper miXingof the raw water and ozone. y Y With the above and other objects in view which Vwill more readily appear as the nature ofthe invention is better understood, .the sameconsists in the n'ovelconstruction, combination Y and arrangement of p parts hereinafter more fully described, illustrated and claimed. Y Y A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which y improvedffinixing device, the general line of the line 2 2. of Figure gl.

and stacked one upon the otherV iny such a manner as to provide a sinuous or tortuous passage therethroughifor the water.l andfozone. `Wlien the several units are assembled as shown in Figure l they provide yin effectia tubular'mixing casing whose interior oii'ers amaximum degreeof resistance to iuid passage,the'unitA bein(r the initial or receiving unit and' they unit*` unit. And, when the desired number of units are assembled, the inletand outlet ends of the "casing inlaykbefclosed by an inlet cap, and an outlet vcap D respectively, eachY being the discharge" having suitable threadednipple portions for Y connecting with the piping-of the apparatus.

To facilitate the holding'ofthe baile units in position', the said end caps U and `D-may be provided with suitableears E for `receiving the tie bolts F, asshownin Figure l.

As previously indicated Vtheindividual baflieunits A and VB Varep`re'feiably Vmade oier porcelain or like materiall which will not become oxidized bythe ozone, and as the end caps `G and D are preferably of. metal such as kbrass,it.is desirabl'eto provide the saine withl a1i`interior non-oxidizinglining L as shown. Thus,.the mixing device `is thor# oughly protected against the corrosive action ofthe'o'zone whilea't the saine timefthe protection afforded in thisrespectv also mainn tains the standard of purity of the water by reason of preventing the formation of for- .eign chemical .substancesyvhichmight other- Wise .result .if the` ozone could lact onviany oi? theV partsof the mixer.
